A 99mTc-HDP bone scan was performed in a 48-year-old man because of diffuse pain in the extremities and involuntary weight loss. The planar whole-body scan showed no pathological skeletal uptake. However, a rare symmetrical uptake was detected corresponding to the nail bed of all fingers and toes (top row). Upon clinical examination of the nails there was no obvious visible cause of the scintigraphic findings. The patient was subsequently diagnosed with Wegener’s granulomatosis. After 7 weeks of steroid and cyclophosphamide therapy a repeat bone scan revealed a slight decrease in uptake intensity (bottom row).
